T0 a/ZZ whom it may concern; Y

Be it known that I, DAVID B. SALTsMAN, a citizen of the United States,residing atl the city of Dowagiac, in the county of Cass and State ofMichigan, have invented certain new and useful Improvements inGrain-Drills, of which the following is a specification.

This invention relates to improvements in grain-drills. y

It relates particularly to improvements in disk furrow-openers forgrain-drills, although it is adapted' for use in other relations.A

The objects of this invention are to provide an improved diskfurrow-opener for grainrills and the like which'is compact, strong anddurable, and simple in its construction.-

A further object is to provide an improved bearing for dis'k structuresofthe class described whereby the strain' upon thedisk in use is reducedto a minimum. i y

Further objects and objects relating to structural details will denitelylappear inl the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is pointed out in the claims.

A structure embodying the features of my invention is illustrated in theaccompanying drawings, forming a part of this specification, in whichFigure l is a detail side elevation view of a structure embodying thefeatures of my in-l vention. Fig. 2 is an enlarged detail side'elevation view of a portion ofthe boot, show. ing its structure for theattachment AofA the disk-bearing. Fig. 3 is an enlarged detail viewtaken on a line corresponding to line 3 3 of Figs. l and 2. Fig. 4 is anenlarged detail sectional view of amodiiied structure corresponding tothe View shown in Fig. 3.

In the drawings the sectionalV views are taken looking in the directionof the little arrows at the'ends of the section-lines, and similarletters of reference refer to similar parts throughout the severalviews.

Referring to the lettered parts of the draw- I ings, the boot A is ofthe usual or any convenient form andconstruction and is provided with aforwardly-projecting bracket to `iiange or disk-like head c.

Vthereon is reduced to a minimum.

the lower end of the boot is a projection A', which is adapted toreceive the bearing-blocks C. The bearing-blocks are secured in positionon the boot by screw-bolts E. If desired, one bolt may be used for thispurpose. Each bearing-block C is provided with an annular Abearing-plate B', having an outwardly-projecting Hange b, adapted toembrace the head cof the bearing- 6o .block B, is mounted thereon. AThebearingplate is also provided with a shoulderb, adapted to receive thedisk B, which is secured to the plate by rivets orlin any other suitablemanner. of each disk over the bearing-blocks C is a capB. The cap B" ispreferably detachably secured in position by `a set-screw orbolt, whichis passed through the disk and into the ,bearing-plate B', therebyclamping the disks 7o Yand forming a very rigid support therefor.

The cap B holds the bearing-plate in position against the bearing-blockand in con-v junction therewith forms the bearing for the disk. Oil issupplied to the bearing in any 75 convenient or usual manner, the meansnot being here illustrated.-

In the modified construction shown in FiO.

4 the bearing-plate B' is secured to the outer intead of the inner faceyof the disk. The 8o parts are substantially the same as those in .thepreferred construction, though it lacksl the advantages of clamping thedisk between It is,

With the parts thus arrangedl the disks are supported in such a mannerthat the strain The structure is very economical to produce, as theparts are simple and readily assembled. If desired, the structure'may bereadily disassembled by removing the cap B and the retaining-bolt E for'the-bea`ring-b1ock,` 95 and the parts are completely disassembled.

I have illustrated and described my invention applied to double-diskstructuresadapted for use as furrow-openers for grain-drills. It isevident, however, that the same is appliroo cable for use in otherrelations. I have illustrated and described the same in the form'Secured to the outer face i preferred by me on account of its economy ofproduction and durability in use. I am aware, however, that it iscapable of very considerable variation in structural details withoutdeparting from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a boot; bearingblocks C having annular flanges cthereon se'- cured thereto; bearing-plates B having sh'oulders b andoutwardlyprojecting flanges b thereon, mounted on said-bearing-blocks;bearing-caps B, adapted to fit over said flanges b', secured to saidbearing-plates; and disks B adapted to fit said shoulders clampedbetween said plate and cap, as .speciied 2. The combination of a boot;bearingblocks C having annular flanges c thereon se cured thereto;bearing-blocks B having outwardly-projeeting flanges b thereon, mountedon said bearingblocks; bearingcaps B adapted to t over said flanges b',secured to said bearing-plates; and disks B clamped between said plateand cap, as specified.

3. The combination of a boot; a bearingblock C having an annular flangec thereon secured thereto; a bearing-block B' having anoutwardly-projecting flange b thereon, mounted on said bearing-block; abearingcap B" adapted to t over said flanges b', secured to saidbearing-plate; and disks B clamped between said plate and cap, asspecied.

4. The combination of a boot; a bearingblock, having a disk-like head atits outer end, secured thereto; a bearing-plate having anoutwardly-projecting flange adapted to embrace said head, mounted onsaid block; a bearing-cap secured to said plate; and adisk clampedbetween said bearing plate and cap.

5. The combination of abearing-block having a head at its outer end; a`bearing-plate mounted thereon; a bearing-cap adapted to embrace saidhead, secured to said bearingplate, and a disk secured to said plate.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
